“I heard one theory where the widow of Diem had JFK murdered, cuz JFK ordered the assassination of Diem.”
She would have had exactly 20 days to pull that off, from her Beverly Hills vacation site.
The ‘Tears of Autumn’ is fiction but makes an intresting case since almot national governments and former heads of state do have professional hit teams in the rolodexes. Certainly Madame Nhu did and the possible of her husband’s murder by American plotting had been discussed by that tough couple. Madame Nhu particularly hated Jackie Kennedy and made no bones of her pleasure over JFK’s murder and Jackie’s distress. (But there were some Americans such as my mother who felt the same way. To my granite hard momma, JFK and Co. had isulted the gods with their hubris and paid the price.)
